POCKET CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 641,285, dated January16, 1900.

Application filed August 15,1899. Serial No. 727,343. (No model.)

To @ZZ whom it may concer-7L:

Be it known that we, HENRY D. GARDY and TAYLOR C. BURKE, citizens of theUnited States, residing at Chester, in the county of Delaware and Stateof Pennsylvania, have invented Improvements in Pocket Cash-Registers, ofwhich the following is a specification.

This invention relates to cash-registers, and particularly to that classknown as calculating7 or adding registers.

The objects of the invention are to produce a cash-registering devicewhich is so compact that it may be carried in the pocket of the user;second, to provide novel means whereby the amounts are automaticallyregistered and the totals indicated; third, to produce such a devicepossessing advantages in points of sim plicity,durability, andefficiency, and, finally, to construct the device in such manner as torender it comparatively inexpensive.

With the above and other objects in view the invention consists in thenovel details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and specilically claimed.

In describing the invention in detail reference will be had to theaccompanying drawings,'forming part of this specification, wherein likecharacters denote corresponding parts in the several views, in which-Figure 1 is a plan view of the face of the registering device embodyingthe invention. Fig. 2 is a plan view with the faceplate removed. Fig. 3is a central section on the line 3 3. Fig. a is a section, taken throughthe axis of the several indicating-wheels, on the line 4 4.

In the drawings, 1 indicates a suitable casing,which may be of anysuitable material, to contain the operating mechanism. Centrally of thecasing is a spindle 2, having a thumbknob 3 attached and projecting fromthe rear of the casing. The form of this knob is immaterial, and it willnot be described in detail. A disk 4; is loosely mounted on the spindleand arranged with a toothed periphery 5, the said teeth being inclinedto form ratchets. On the spindle with the disk is an arm 6, with a spur7 cut therefrom, which acts as an indicator. Near the end of the arm isa spring-dog 8, designed to engage the ratchetteeth of the disk,wherebysaid disk is rotated. The springs 9, which are attached to the bottom ofthe casing, exert sufcient pressure on the disk to` prevent accidentalmovement thereof. Studs 10, ll, and 12 are secured to the bottom of thecasing, and on these studs are mounted the wheels 13, 14, and l5,respectively, the rst-named wheel having its 6o lower su rface onapproximately the same hori- Zontal plane as the Atop of thesecond-named wheel, and the second-named wheel having its lower surfaceon approximately the same horizontal plane as the upper surface of thelast-named wheel. The first-named wheel of the series is provided with alug 1G, which engages and throws the second-named wheel the distance ofone tooth when it has made a complete turn, and the second-named wheel7o is likewise provided with a lug 17, which engages and throws thelast-named wheel the distance of one tooth when the said second wheelhas made'a complete turn. The rst kof this series of wheels has itsinitial motion imparted to it by a lug 1S on the lower surface of thedisk et on the spindle. Each one` of the series of wheels is vprovidedwith a spring 19, which exerts sufficient pressure to prevent retrogrademovement or undue play. 8o

The wheel13 is provided with numerals for each of the teeth from 0 to9,7 and the second wheel is provided with numerals at each tooth rangingfrom O to 90, and the wheel 15 is provided with numerals rang- 85 ingfrom O7 to 9.7 The dial or face of the indicator is numbered from O to95.

In the arrangement shown the graduations of the dial indicate cents, andthe arm 6, taking motion from the spindle 2, which is moved 9o by thethumb-piece a,is to be moved one space for each cent. For each dollar acomplete rotation of the spindle will be necessary, and when said armhas been turned from O on the face around to the 0 it will indicate 95one hundred cents or one dollar. Vhen the arm has reached this point, itis arrested by a stop 20, turned up from the face-plate, and the arm canbe turned no farther in the direction it had been traveling. a furtherregister, the spindle must be turned back, and the arm thereon will alsobe carried back, and its spring-dog will ride over the teeth of the diskwithout moving said In order to make roo disk. Now when the arin abutsthe lng 2O on the opposite side it will be set, and repetition of themanipulation iirst indicated Will be in order.

The studs on the disk and on the several wheels are so positioned as toengage the teeth and partially turn the Wheels in their order just asthe arm 6 has abutted the stop 20.

From the foregoing it Will be understood that with a complete rotationof the disk 4 the wheel 13 is turned the distance of one tooth to exposethe numeral 1. Thus one dollar is registered. With ten such movementsthe Oon Wheel 13 and 10 of Wheel 14 will be exposed, thus indicating tendollars, and when the Wheel 14 has been turned the distance of ten teethor a full rotation the Wheel 15 Will expose 1, this being thehundreds-Wheel, and so mark the total amount registered by the arm, andthe'several Wheels can be instantly determined.

Having fully described our invention, what We clailn as new, and desireto secure by Letters Patent, is-e In a cash-register, a casing, aspindle centrally thereof provided With an operatingknob which projectsfrom the rear of the casing, a disk loosely mounted on the spindlehaving a toothed` periphery inclined in one direction to formratchet-teeth, an arm mounted on the spindle and taking motiontherefrom, a spring-dog secured to the edge of the arm with its endcurved to engage the teeth of the disk, a face-plate for the casinghaving a stop 2O formed therewith adapted to arrest the arin, a dial onthe face-plate, a spur struck from the arm and bent up over the edge ofthe dial, a stud projecting from the lower edge of the disk, a series oftoothed Wheels, each on a different horizontal plane, lugs on the firstand second Wheels engaging teeth on the second and thirdv wheelsrespectively, the lug of the disk engaging the teeth of the firstnamedwheel, springs `attached to the bottom of the casing and bearing againstthe under faces of the disk and several Wheels, the upper faces of thesaid Wheels being provided With suitable characters, as and for thepurpose specified.
